JOSEPH HALL, OF LEEDS, ENGLAND.

MACHINE FOR TREATING SKINS, LEATHER, 80o.

SPECIFICATION forming part of Letters Patent No. 561,583, dated June 9, 1896.

Application filed March 3 1 896.

T0 aZZ whom, it may concern:

Be it known that I, JOSEPH HALL, a subject of the Queen of Great Britain, residing at Leeds, in the county of York, England, have invented certain new and useful Improvements in Machines for Treating Skins, Leather, or Analogous Materials, of which the following is a specification. I

My invention has relation to a machine for the treatment of hides, skins, leather, &c., and of the type or character known as slickingf? setting, stoning, glossing, rolling, and printing machines, and in such connection it relates more particularly to the construction and arrangement of the tool head or holder of such machines.

The principal objects of my present inven' tion are, first, to provide in a machine of the character described a revolving head or holder of simple construction, efficient in act-ion and durable, and well adapted to the uses to which the same may be employed; second, to provide a head or tool holder adapted to be retated in a bracket in a plane parallel to that in which the tool works and provided with means for locking the same in required position in said bracket, and, third, to provide in such a revolving head or tool-holder means for reciprocating said head and means for maintaining the tool in a working position during the reciprocation of the head.

My invention, stated in general terms, consists of a revolving tool-holder for skin and leather machines constructed and arranged in substantially the manner hereinafter de-' scribed and claimed.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the ac companying drawings, forming part hereof, and in which- V Figure 1 is a side elevation of the toolholder, illustrating means for reciprocating the same and for maintaining a particular tool in working position during the reciprocation of the holder. Fig. 2 is a front elevation of the same, and Fig. 3 is a vertical section through the tool-holder and boss into which the locking-pin is inserted and illustrating means for locking the tool-holder in its supporting-bracket.

Referring to the drawings, A represents a Serial No. 581,620. (No model.)

slide-block Working in guides at underneath the frame of the machine. To this slide-block are pivotally secured the arms b of a yokeshaped or forked bracket B, carried at the end of the reciprocating or crank shaft 0, connected eccentrically with the driving-wheel of the machine. (Not shown.) lVithin the bracket B is located a tool-holder E, provided at its periphery with thetools e, 6, c and 6 adapted to rotate in said bracket in a plane parallel to that in which the shaft G is reciprocated, as hereinafter more fully explained. In the lower ends of the bracket is secured a transverse bolt or shaft F, upon which revolves a boss or sleeve G, upon which boss is mounted the tool-holder E, adapted to revolve thereon.

The boss G is provided with an arm H, the end of which is pivotally secured, as at h, to the link K, which is pivotally secured, as at 70, to the slide A, as indicated in full and dotted lines in Fig. 1 of the drawings. The boss G is provided with an annular flange 9, having a perforation g, adapted to'regist-er with similar perforations e in the head or roller 6. Upon the boss G is also mounted the plate or arm M, provided with a recess or opening m, and adapted to be locked in required position on the boss G by means of the thumb-nut m, as indicated in Figs. 2 and 3. The head E is secured to the boss G by means of a pin N, which passes through the perforation g of the boss and one of the perforations e of the head E, as shown in Fig. 3. The boss G is provided with a bearing-flange 9 upon which the head E is adapted to rest in rotating upon the said boss. The pin N is locked in the perforation by the plate or arm M, the recess of which enters an annular groove 01- in the head of the pin.

In operation when the shaft 0, bracket 13, and slide A are reciprocated the link K will swing upon its pivotal connection, thus causing the boss G, head E, and the tool which is being used to move in a direction parallel to the table on which the hide is stretched, and to always maintain the proper position for working upon the hide or skin. When the tool is to be changed, the thumb-nut m is loosened and the plate M swung out of engagement with the pin N. The pin N is then withdrawn from the perforations g and e swung around until its recess enters the an-' nular groove n of the pin N, and the plate M is then looked in this position by advancing the thumb-nut m.

Having thus described the nature and ob jects of my invention, What I claim as new,

and desire to secure by Letters Patent, is- 1. The combination of the reciprocating bracket, a head carrying required tools adapted torotate within the bracket in a plane parallel With that of the reciprocation of said bracket, a pin adapted to lock said head to said bracket, and a plate adapted to lock said pin, substantially as and for the purposes described.

2. Inamachine of the character described, a'bracket, means for reciprocating the same, a bolt carried by said bracket, a boss revolving upon said bolt and provided with aperforation, a head carrying tools adapted to revolve on said boss, said head being provided With perforations corresponding to the number of tools and adapted to successively register with the perforation of the boss, a pin adapted to enter the perforations of the boss and head, and a locking-plate adapted to secure said pin in said perforations, substantially as and for the purposes described.

3. Inamachine of the character described, a slide, a bracket suspended therefrom, a reciprocating shaft adapted to move said bracket and slide, a boss carried by said bracket and revolving therein, a tool holder adapted to revolve upon said boss Within said bracket, an arm secured to said boss, and a link pivoted at one end to said arm and at the other to said slide, substantially as and forthe purposes described;

In testimony whereof I have hereunto set mysignature in the presence of two subscribing witnesses.

JOSEPH HALL.
